atara has occasionally expressed the opinion that I suffer from a mild case of OCD. I cannot say one way or the other, but I found myself building another
Tower of Hanoi out of my pocket change this morning. I had never given it much thought until I noticed that I was doing it again this morning; when I put aside change for my morning coffee, I always unconsciously arrange it from largest (loonie) to smallest (dime) in a stack.
Personally I think that it has less to do with OCD and more to do with aesthetics.
